I don't see the need of expensive Race Fuel on such a Low Compression Motor...

Wasted monies in my opinion... Wink

It depends on what fuel you have . Super plus like in Germany (98) roz ron octane is good for 10,5 : 1 . 9.5 :1  95 octane

Even with 10.5 CR, Race Fuel does not make sence... Roll Eyes

If you want to use Race Fuel, get the CR up to 12.5 and use VP C-12...

It releases less energy during combustion.  In a high CR engine, the higher efficiency makes up for the lower heat of combustion such that the overall hp is more.
